Abstract: A bone substitute (a material for repairing biological tissues) made from ?-TCP as the raw material comprises a plate-type base member on the surface of which a plurality of grooves extending in a single direction are formed and separated from each other by partition wall members having an almost uniform thickness. This material sustains a sufficient binding force after application to a biological tissue and exhibits an excellent effect of forming a biological tissue.

Abstract: An object is to promote the growth of adhered cells and improve adhesiveness of stem cells. A cylindrical scaffold made of a porous calcium phosphate (for example, beta-TCP) material has a form in which a plurality of through-holes extending in a single direction are separated from each other by partition wall members having an almost uniform thickness. The material for repairing biological tissues wherein each through-hole has a quadrangular shape, and each partition wall member has a plurality of concavities and a plurality of pores in the surface, and a process for producing the same are provided.

Abstract: To efficiently manufacture globular ceramic particles which can be formed uniformly in surrounding gaps when they are arbitrarily filled into a defect part of biological tissue or the like, without impairing the adhesiveness of cells. There is provided a method of manufacturing globular ceramic particles comprising; containing a predetermined amount of granular shaped ceramic particles inside a cylindrical container 5 that is arranged approximately horizontally, and rotating the cylindrical container about its axis.

Abstract: In a pattern formation member adopted to a sectioning image observation apparatus which selectively irradiates a light from a light source to a sample, scans the sample, and acquires a light from the sample as a sectioning image, the pattern formation member comprises an irradiation section and a cutoff section, each of the irradiation section and the cutoff section is in a straight pattern, and these straight patterns are disposed alternatively.

Abstract: In a confocal microscope, a beam of light from a light source is lead to a rotary disk by way of an optical lens and a half mirror, and made to strike specimen by way of an objective lens. The rotary disk has random pin hole pattern sections where pin holes are randomly bored through a light blocking mask, and an aperture section having an area k2 times greater than the area of the random pin hole pattern sections and allowing any light to pass therethrough. The beam of light reflected by the specimen is made to enter a CCD camera by way of the objective lens, the rotary disk, the half mirror and a condenser lens. The CCD camera is adapted to selectively pick up a composite image containing a confocal image component and a non-confocal image component of the specimen obtained through the random pin hole pattern sections and a conventional image of the specimen obtained through the aperture section.
